Cards

Term
repetition priming
Definition
The facilitation of identification (or other processing) of specific stimulus materials to which one has recently been exposed.
Term
associative priming
Definition
the facilitation of item identification or other processing following a single exposure to a combination of information
Term
conceptual priming
Definition
repetition-produced facilitation of identification or other processing of entire categories of words
Term
exemplar
Definition
an individual item within a category of similar items
Term
visuospatial sketchpad
Definition
a system that stores and manipulates visual or spatial information
Term
Brown-Peterson test
Definition
A procedure in which subjects are initially given a list of items to remember, then distracted for a variable period, then asked to recall the list
Term
Recency Effect
Definition
Items at the end of a list are typically recollected better. (serial recall)
Term
Operation span task
Definition
A measure of working memory capacity that assesses both the processing and storage demands on transient memory
Term
Chunking
Definition
increasing the amount of information stored by efficiently compacting multiple elements of information into each item stored- such as storing a set of three digits as a single three-digit number.
Term
Self-ordering task
Definition
An object recognition task in which the subject determines the initial order in which items are initially selected and then must remember the order of the choices
Term
release from proactive inhibition
Definition
a phenomenon in serial recall in which performance increases when subjects switch from lists of one category to another.
Term
episodic buffer
Definition
a system within working memory that stores the sequence of events composing a recent experience; a later addition to baddeley's original working memory model
Term
serial recall
Definition
in memory for a list of items, the accuracy of recall for each item depending on its position in the list.
Term
perceptual priming
Definition
repetition-produced facilitation of identification (or other processing) of the sensory qualities of a stimulus
Term
semantic memory
Definition
accumulated world knowledge that is not tied to any particular learning event and is subject to conscious recollection
Term
prototype
Definition
a simple model of a category of items that shares the basic features of all items in the category
Term
phonological loop
Definition
a system that stores and manipulates speech-based information
Term
Primacy effect
Definition
(serial recall) superior recall of items at the beginning of the list, usually attributed to lack of interference from preceding items
Term
serial position curve
Definition
an analysis of serial recall that measures the likelihood that each successive list item is remembered
Term
central executive
Definition
a system that controls and manipulates information in the visuospatial sketchpad and the phonological loop, accesses information from long-term storage sites, and distributes processed information to long-term memory sites.
Term
forgetting curve
Definition
analysis that measures the rate at which human memory information is lost over time
Term
serial probe recognition task
Definition
a procedure for testing working memory in which, on each trial, a list of items is initially presented; then following a variable delay, memory for the item at a particular position in the list is tested. Performance is measured in terms of accuracy at different positions in the list.
Term
Delay cells
Definition
in a working memory task, neurons that fire throughout the delay period when a sample stimulus must be remembered for subsequent recognition testing.
Term
subvocal speech
Definition
a system in working memory that supports the ability to consciously verbalize words without speaking aloud
Term
Aphasia / Agnosia
Definition
Studies of _ and _ indicate that memories for words and visual stimuli are organized by conceptual categories
Term
parahippocampal place area
Definition
the _ is activated when subjects view houses and environmental scenes relative to when subjects view faces or common objects
Term
Extrastriate body area
Definition
the _ is activated when subjects view pictures or drawings of human body parts relative to when subjects view inanimate objects or their parts
Term
interference/decay
Definition
Within the brown-peterson task, forgetting appears to primarily result from __ rather than __
Term
Distributed Network Models
Definition
One approach to simulating semantic networks involves _ that represent concepts as patterns of activation across interconnected units
Term
Environmental
Definition
an _ reference system involves the locations and directions of objects relative to one another and independent of the viewer
Term
egocentric
Definition
an _ reference system involves the locations and distances of objects relative to the position and direction of the viewer
Term
Hippocampus: (anterograde amnesia) secondary memory & primacy are attenuated (LTM damaged)

TPJ: Primary memory and recency are attenuated (Working memory damaged)

Prefrontal cortex damaged: Central executive function attenuated. Interference effects.
Definition
Damage to the hippocampus:

Damage to the Temporal-Parietal Junction:

Damage to the Prefrontal Cortex:
Term
dorsolateral prefrontal cortex
Definition
brain structure responsible for somatosensory and visuospatial information
Term
ventral lateral prefrontal cortex
Definition
brain structure responsible for auditory and visual pattern information
Term
orbital prefrontal cortex
Definition
cortex involved in working memory & central executive function that seems to have general functions
Term
Dorsolateral prefrontal

ventral lateral prefrontal

Orbital prefrontal
Definition
semantic knowledge is represented in broad areas of the _, _, and _ cortices
Term
